Electric propulsion is used in wide range of vessel types and applications. In marine vessels, the load of the power plant changes substantially over time, such as from the wave disturbances or the weather influence, which may cause large and also rapid changes in the load of prime movers. In this paper, to reduce the effects of the disturbances of the power plant and to improve the energy efficiency...
Regarding the reduction of the cost of energy (COE) for photovoltaic (PV) systems, two important issues are maximizing the efficiency of power generation and fault diagnosis. This study presents an integrated framework that achieves both maximum power point tracking (MPPT) control and diagnosis of change in internal resistance simultaneously. An extremum seeking control (ESC) strategy is developed...
In this paper, a novel push-pull-forward half-bridge (PPFHB) bi-directional DC-DC converter with coupled inductors is proposed. All switches can operate under zero-voltage-switching (ZVS). The operation principle with phase-shift modulation scheme, characteristics of coupled inductors, the steady state relationship and small-signal model are analyzed. The voltage controller based on the small-signal...
